mageba TENSA-MODULAR multiple-gap expansion joints can accommodate movements in every direction and rotations about every axis. They can be used for longitudinal movements of as little as 160 mm, or for very large movements of well over 2,000 mm. The total movement of the bridge deck is divided among a number of individual gaps which are created by horizontal surface beams. The individual gaps are sealed by watertight elastomeric profiles, and surface beam movements are regulated by an elastic control system. The drainage of the joint is via the drainage system of the bridge deck. Type LR-LS joints feature so-called “sinus plates” on their surface, which reduce noise from over-passing traffic by up to 80%.

Applications

TENSA-MODULAR expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint. The watertight system, which was invented by mageba several decades ago, is designed on a modular basis and can be tailored to satisfy the specific requirements of almost any structure.
